KF720

3-way line array module

KF720 delivers the three-way design, power and fidelity of the KF Series line array systems in an ultra-compact enclosure weighing less than 44 lbs. (19.8 kg). The exceptional output capability in a small, lightweight package allows KF720 to fill a range of application requirements from small theaters and houses of worship to live concerts and corporate events.

KF720 features an internal, passive MF/HF crossover filter network to deliver bi-amplified powering of the three-way system. Dual 6-in LF cone transducers in a sealed enclosure deliver horizontal pattern control via tuned spacing. Dual 6-in MF cone transducers are mounted in a large horn that fills virtually the entire face of the enclosure, maximizing horizontal pattern control as well as driver efficiency. Six 1-in dome tweeter HF transducers share the same horn with the MF transducers; tightly stacked in the center of the enclosure, the six HF transducers leverage beneficial interaction to generate extraordinary output. The three subsystems feature a symmetrical configuration, allowing coherent summation and even response across the nominal 110 degree (h) by 12 degree (v) coverage area.

The KF720 flybar works on its own or, via an adapter, can attach to an NTS250 dual 15-in subwoofer. The KF720 flybar also features adjustable footpads so that users can invert it and use it to safely ground-stack up to six KF720 modules. The ingenious rigging system allows users to select a range of module-to-module angles, which simply snaps into place to create a safe, strong connection between modules. In the unlikely event of a module failure, users can quickly and easily remove the module from within the rigging structure and replace it without ever disassembling the array.

Six year loudspeaker warranty.

KF LINE SOURCE VOICING UPDATE Leveraging data and experience from development of Adaptive Systems™, updated Greybox™ processing enhances performance of KF720, incorporating improved equalization, crossover, Focusing™ and limiting parameters for even better system performance without physical changes. The update brings improved warmth and clarity to the system, while making it sonically more consistent with KF730, KF740 and Adaptive Systems. Updated Greyboxes™ are available here.

  • Ultra-compact, three-way line array module
  •  Advanced, easy to operate rigging system
  •  Exceptional pattern control due to symmetrical design, large horn and Phase-Aligned™ woofers
  •  Incorporates core EAW technologies including CSA™ and Focusing™ for outstanding mid and high frequency transient response
